![7) Compounds Q and R are known to react in the gas phase to form Compound X by the
following overall balanced chemical equation: 2 Q(g) + R(g) -> 2X(g)
The reaction kinetics have been studied experimentally and the following elementary step
sequence was proposed as the reaction mechanism:
6 Step 1: Q+R → Z
(slow step, large Ea)
Step 2: Q+Z+2X (fast step, small Ea)
Based upon the proposed mechanism, what would be the best way to write the rate law
expression for the reaction 2 Q(g) + R(g) → 2X(g)?
A. rate = k[Q] [R]
B. rate = k[Q][R]
C. rate = k[R]
D. rate = k[Q] [R][Z]
